# Linear Systems Solvers¶

The settings parameter linsys_solver defines the solver for the linear system. In C/C++ it corresponds to an integer c_int (see Data types) and in the other high level languages to a string.

Solver String option C/C++ Constant
SuiteSparse LDL “suitesparse ldl” SUITESPARSE_LDL_SOLVER
MKL Pardiso “mkl pardiso” MKL_PARDISO_SOLVER
